from cumulusci.core.config import BaseProjectConfig config = BaseProjectConfig()
config['new_key'] = 'new_value'
value = config['existing_key']
for key in config: value = config[key] # do something with the key-value pairIn summary, these code examples demonstrate the use of the BaseProjectConfig class in CumulusCI to initialize, set and retrieve values, and iterate through a configuration instance. The package library used is cumulusci.core.config.
